Audio Transformers are like Monster Cables

Ok, I need a 10mW audio transformer with a 1:1 turns ratio for my 90R load. So I look at many vendors and here is a typical spec: Let's forget cost, because we all know that PICO is like Monster Cables. The first unit I look at is the F-28003 with a pri:sec Z of 10R:10R. There are many other 1:1 transformers listed but from the data shown, this is the most efficient, best bandwidth and lowest distortion of all the 1:1 transformers listed. So why list any other 1:1 transformer? I must be missing something, so spank me with your keyboards. Harry

Absolutely. You can make a fabulous transformer around a tape-wound Metglas toroid. Permeabilities are in the 100K+ range, and as high as a million if you know how to treat the stuff. It's just a few mils thick, so eddy losses are tiny. There *is* life after the Radiotron Handbook.
